WoO 54 Lustig – traurig for piano, 1790, first published in the GA. Supplement, 1888. GA. no. 300 (series 25/37). B. 282 – KH. (WoO)54 -P. 101.

The original manuscript is preserved in the Deutsche Staatsbibliothek in Berlin. Two small pieces in tempo 3/8, forming a unicum, each in two parts of eight bars and with a repeat sign; the first (Lustig) always remains in the key of C major and is repeated as if da capo after the second (Traurig), which is instead in C minor, with an intermediate passage to G minor. The date cannot be determined with certainty: 1790 according to KH., 1798 according to P., 1820 according to Mandyczewsky (in his preface to the Supplement to the GA.). We accept the first.
